One-button operation with automatic detection and shutdown. The multi-function button can also be used to close the detector. Detect infrared waveforms and zener diodes with built-in self-calibration for accurate results. After detection, align the infrared remote control to the IR indicator light and press the remote control button. When decoding is successful, the data code and infrared waveform are displayed. Broad compatibility for electronics work, capable of capturing NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel and P-channel MOSFETs, IGBTs, JFETs, triacs, and batteries, among others. Use scenarios: - Troubleshooting infrared remotes: capture and verify IR codes and waveforms for diagnostics. - Component and device analysis: identify and characterize transistors, MOSFETs, diodes, and related components on a board. - Zener and diode testing: confirm diode behavior and self-calibrate for consistent measurements. Professional, clear, and reliable tool designed for precise detection, decoding, and display of infrared signals and electronic components.
